Deformation of thin walled bodies

A thin walled body is deformed in a process in which the body is gripped securely in a holding station and, while gripped in the holding station, tooling engages to deform the peripheral wall of the body at a predetermined wall zone. The tooling is provided at a tooling station which is adjacent the holding station during deformation. The predetermined wall zone is co-aligned with the tooling by rotation of the body about an axis prior to securing at the holding station.
